COMBINED LAWN-SPRINKLER AND NOZZLE.

Specification of Letters Patent.

Application filed April 16, 1912. Serial No. 691,229.

To all whom it may concern:

Be it known that I, JONATHAN BYLER, a citizen of the United States, and resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Combined Lawn-Sprinklers and Nozzles, of which the following is a specification.

My invention relates to combined lawn sprinklers and nozzles, and comprises the novel parts and combinations of parts which are hereinafter described and particularly pointed out in the claim.

The object of my invention is to produce a device of improved character which may be used as a hose nozzle or as a sprinkler for lawns adapted for lying upon lawns and throwing a rose-shaped spray in all directions fwithout requiring attention, except to occasionally shift to a new position.

In the drawings I have shown my invention embodied in the form which is now preferred by me.

Figure 1 is a vertical longitudinal section, slightly offset in its upper part, to show the ring-supporting arms in full lines. Fig. 2 is a longitudinal section on a central horizontal plane, looln'ng upward. Fig. 3 is a section on a transverse plane passing through the side discharge opening, the plug for controlling this opening being removed, the view being toward the nozzle end. Fig. 4; is an elevation of the nozzle end, the nozzle cap being removed.

My device is designed for attachment to a hose and for operation either as a nozzle to be held in the hand for sprinkling, or to lie upon the lawn and throw a rose spray in all directions, without requiring any attention except to shift it from place to place.

The base of the device consists of a hollow body or casing 1, provided at one end .with a supply opening, as 10, preferably threaded for the attachment of a hose nipple or pipe from which it receives the water supply. At the opposite end from the supply, is the nozzle 12, adapted for use when the device is to be held in the hand or used to throw a spray or stream horizontally. The central section of this casing is preferably made as a section of a sphere, flattened at top and bottom and provided with the protuberances necessary for attachment of the hose and the nozzle. This forms a central chamber 11 of considerable size compared with the inlet and outlet openings. The upper side of the casing is provided with a discharge opening, which is at the bottom of a depression 52, of a general conical shape. The under edge of the walls surrounding this discharge opening, are finished to form a valve seating surface 51. In the opposite, or under wall of the casing, is a plug-receiving hole 70, which is screw-threaded to receive a plug 6, which has an end surface or shoulder 63, adapted to engage with the surface 51 of the upper casing wall, to act as a valve to control the discharge. The upper or inner end of this plug has a central extension 62, in the form of a button, having an inner neck and an outer enlarged end, the latter being of a size to just pass through the opening 50 and being adapted to be engaged by the discharge to spread and throw it outward in the form of an umbrella, thus making a rose-shaped spray. The head 63, of this plug lies within a circular, saucershaped recess 7 formed in the bottom of the casing and of a depth to accommodate the head of the plug when the opening controlled thereby is in use, without having the head project beneath the walls of this recess. The upper or inner end of this plug is provided with a support designed to hold it securely and fixedly in exact position, so that the jet-spreading button 62 will maintain exact central relationship with the exterior walls of the opening 50. The outer surface of the depression 52 is turned symmetrical and in alinement with the boring of the plug-receiving hole 70 and the hole in the plug-supporting ring 2, and the plug 6 is turned at the same time the outside of the jet-spreading button 62 is turned. It therefore follows that the button 62 is main tained exactly central of the cavity 52, and the spray issuing therefrom will be evenly distributed on all sides. Were the plug 6 supported only by the opposite side wall of the casing it would be subject to displacement by accident, and would also be liable to fit loosely enough to permit side displacement, which would result in unequal distribution of the spray about the button 62.

The ring 2 is preferably made integral with the casing, being supported therefrom by arms 20 and 21, which are narrow webs placed upon the central axial line and depending from the upper wall of the casing. In this position they interfere very little Patented Jan. 20, 1914.

with the flow of water to either discharge opening. The ring 2 is placed far enough below the seating surface 51 to leave an ample area between them for the water flowing to this opening.

The end of the casing opposite the supply opening 10, is formed into a neck 12, which constitutes the nozzle. The outer end of this neckis closed by a diaphragm 13, which is integral with the casing and has a central pin 3, projecting slightly therefrom and terminating in a reduced jet-spreading button 30. Through the diaphragm about the pin 3, are holes 14 through which pass the Water discharged through the nozzle. The outer surface of the neck 12 is threaded and upon this screws a cap 4, which has a central hole adapted to alinewith the pin 3, and small enough to engage the shoulder formed where this pin is reduced to form the button 30. By screwing the cap down it will seat uponfthis shoulder and stop the flow of water through this opening, By screwing the plug '6 down upon its seat so as to close the side-discharge opening 50, and screwing back the nozzle cap t, this device may be used as an ordinary hose nozzle, to hold in i the hand and direct the discharge wherever desired. When the cap at is opened only slightly, the issuing water will strike with force against the jct-spreading button 30 and a fine spray will be produced. As the cap l isscrewed back the amount of water will increase and the coarseness of the spray will increase. Byscrewing the cap 4 back until the opening 40 is well beyond the button 30, a solid stream will be produced. By closing this nozzle and opening the side discharge opening, a rose-shaped spray of an adjustablefineness and volume may be produced. The devicemay be laid down upon the lawn and left to spray a section of the diameter of the rose jet produced. It may be readily shifted in position by manipulating the hose from adistance.

The plug 6 being supported at two points separated a considerable distance, that is, by the outer casing and the ring 2, is held securely in exact central relation with the opening .52,uand as the button is in exact alinement with the plug, the space between the button and the walls of the opening52 is exactly the same on all sides,-thus producing a. spray which is symmetrical and even on all sides. Without this additional support the plug is apt to become displaced somewhat, thus producing an uneven and unsymmetrical spray, which is very unsatisfactory. v

hat I claim as my invention is:

A sprinkler comprising a hollow casing having an inlet and a discharge opening with their axes at right angles, and having an inwardly facing valve-seating surface surrounding the. discharge opening, thev wall of the casing opposite the discharge opening having a threaded opening .coaxial with the discharge opening, a threaded plug screwing into this latter openin'giand havingia face adaptedto seat upon the valvesseating surface which surrounds the discharge. open? ing, a ring located intermediate the sides of the casing andinto which;saidplugiscrews, and two Webs lying in the plane perpendicular to the ring ,whichincludes the axesof both the inlet and the discharge openings and integrally joining saidring With the sideof thecasing which contains the discharge openingz, v j,
